PRLITING AND ADDRESSTNG MACHINE.

Original application filed May 24:, 1920, Serial No. 383,815.

New Eatent No. 1,563,822, dated. August 5,

192 1. Divided and this application filed April 24-, 1924:. Serial No. 708,779.

This application relates to printing and addressing machines and forms a division of our co-pending case Patent No. 1,503,822, granted August 5, 1924:. The mechanism shown in said co-pending application was one for feeding printing devices from the bottom of a stack and for selecting such of the printing devices from which it was desired to print.

The present invention relates to the means for feeding the printing devices from the bottom of a stack it being understood that said devices are contained in a magazine and are fed from the bottom of said stack one at a time to printing position and are then ejected by suitable mechanism.

One of the objects of our invention is to provide a feeding means which is positive in operation and will operate to feed a printing device without fail.

Another object is to provide a feeding device which, when feeding the device at the bottom of a stack will not be forced out of its engagement therewith by pressure from the rest of the stack.

Referring to the drawing forming a part of this specification Fig. 1 is an elevation of a portion of the printing and addressing machine embodying our invention parts thereof being broken away and parts being shown in section to better illustrate the relation thereof, and

Fig. 2 is a section taken on the line 2-2 of Fig. 1.

The frame of the machine is indicated at 1 and sliding in guideways 2 therein is a sliding frame comprising bars 8 and plates 4: having out-turned flanges 5. Said plates 3 are joined at one end thereof by a bar 6 to which is pivoted the operating link 7 actuated by mechanism not shown to cause reciprocation of the frame in the guideways 2, as explained in my co-pending application above referred to. Pivotally mounted at 8 on plates 1- are feed dogs 8 normally urged upward by a spring 9 and limited in their upward movement by the flanges 5, as will be plain from an inspection of Fig. 1. The dogs 8 are provided with shoulders 10 to engage the lowermost feeding device 11 of the stack of such devices carried in maga- Zinc 12. This lowermost printing device 11 restsnpon supports 13 forming part of a slidable frame 141 sliding on are main 1. The frame comprising plates 4 in its movement forwardly or to the right of Fig. 1 carries with it the said printing device 11 over pawls 15 and brings said device into engagement with projections 16 on ejector bars 17. The ejector bars are then carried along with the printing device in its movenent, to position on the anvil, a portion of which is indicated at 18, and upon return movement by the operating link 7 the projections 16 causeejcction of the printing device, all as explained in our aforesaid co-pending application. The retnrn movement of the ejector bars is caused by engagement of plates at with blocks 19 on the rearward end of the ejector bars.

At 20 we have shown pivoted dogs to move the lowermost printin device rearwardly or to the left of Fig. 1 in order to operate the selector frame 21 by means of tabs 22 mounted on certain of the printing devices and engaging pins 21, for purposes fully explained in our aforesaid application and forming no part of our present invention.

As the lowermost printing device is removed from the bottom of the stack it is evident that the next device will rest on the dogs 8 and tend to rotate them about their pivots 8 and out of contact with the printing device which is being fed. To avoid this trouble we provide on each dog a lug 8 which, during the movement forwardly or to the right in Fig. 1, will engage with the inclined Surface 17 of an ejector bar 17 and then with the top edge 17 thereof, thus holding the dogs 8 in engagement with the printing device. It will be understood, of course, that the dogs 20 are removed from engagement with the forward edge of the printing devices before the dogs 8 engage therewith, this operation being fully described in our aforesaid application, but it may be briefly restated here by saying that this disengagement is caused by the beveled edges 20 of the dogs 20 contacting with fixed stops 28. These dogs are mounted upon a frame 2%, which is moved forwardly by spring 25 to cause engagement of the edges 20 with the stops 23. Rearward movement of the frame 24 is caused by engagement of plates & with cross-bar 26 in said frame,

It will be obvious from the above descrip tion that we have pr ea ed a devicdwhich will -,i j rrinti device frrnn the bottom of a stack of such devices in a manner which is positive and certain, and that we have provided means to prevent interference with the feeding device by the stack of printing devices above the one being fed. At the same time the flanges 5 provide means for preventing upward movement of the feeding devices to a position where they would disturb the printing devices in the stack other than the one being fed.

e are aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the invention and we reserve the right to malre all such changes as fairly fall within the scope of the following claims -We claim:

1. In a printing machine, a magazine adapted, to contain a stack of printing de vices and means to feed a printing device from the bottom of said stack, said means comprising a member adapted to engage the bottom device in saidstack and movable into and out of engagement therewith, and means preventing movement of said member out of engagement with said device after it has engaged the same.

2. In a printing machine, a magazine adapted to contain a stack of printing devices and means to feed a printing device from the bottom of said stack, said means comprising a. member adapted to engage. the bottom device in said stack and movable into and out of engagement therewith, means preventing movement of said member out of engagement with said device after it has engaged the same, and means limiting the movement of said member towards said bottom device.

3. In a printing machine, a magazine adapted to contain a stack of printing devices, means to feed a printing device from the bottom of said stack and comprising a pivoted dog resiliently urged toward said stack, means limiting the movement of said dog toward said stack, and means preventing movement of said dog away from said stack after it has engaged the bottom printing device.

4. In a printing machine, n-ieans to feed printing devices one at a time from the bottom of-a stack and comprising feed dogs adapted to engage an edge of the printing device to be fed and to feed it forwardly, and means to sustain said feed dogs in operative engagement with the printing device being fed as said device moves from beneath the stack.

5. In a printing machine, means to feed printing devices one at a time from the bot tom of a stack and comprising feed dogs adapted to engage an edge of the printing device to be fed and to feed it forwardly, and means adapted to be engaged by said feed dogs during the forward movement thereof to sustain said dogs in operative engagement with the printing device being fed as said device moves from beneath the stack.

6. In a printing machine, means to feed printing devices one at a time from the bottom of a stack and comprising a pivoted dog yieldingly pressed upward into engagement with the edge ofv the printing device to be fed and to feed it forwardly, and means adapted to be engaged by said feed dog to support it and prevent the stack from disengaging it from the printing device being fed as said device moves from beneath the stack.

7. In a printing machine, means. to feed printing devices one at a time from the bottom of a stack and comprising a feed dog, means pressing said dog upwardly into engagement with the edge ofthe printing devise to feed it forwardly, a lug on said dog and a bar to engage said lug and support said dog in operative engagement with the printing device being fed as said device moves from beneath the stack.

8. In a printing machine, a magazine adapted to contain a stack of printing devices, means to feed said devices one at a time from the bottom of said stack and comprising a pivoted dog, an ejector bar movable with said feeding means, and co-acting parts on said dog and on said bar to maintain said dog in engagement with the device at the bottom of said stack,
